Span (programming language)

Span is a programming language targeting the Parrot virtual machine. Its syntax is meant to be very similar to C, but its philosophy is Smalltalk-like, and it uses Smalltalk-style message syntax. Almost all of Span's library visible to the user is written in Span itself. Span is dynamically typed. The hello world program in Span is

class Hello { static public main: args { Console << "Hello World! "; } }

Span uses blocks ala Smalltalk for all flow control constructs except definition. For example, for this pseudocode fragment:

if x > y print "yes" else print "no"

Span would write

(x > y) ifTrue: { Console << "yes" } ifFalse: { Console << "no" };

Span is currently in very early stages of development.
